Dublin has a plan now for how the new $91.25 million I-270 interchange will look after it is
rebuilt.

A four-person committee appointed by the Dublin City Council selected a design that incorporates
scenes from the Scioto River for the walls of the interchange. The committee also chose Celtic-knot
designs for the bridge parapets and piers.

The Ohio Department of Transportation has reviewed the plans and, with some suggestions for
minor improvements, everything is now headed into the next phase of design, said Sara Ott, a senior
project manager with Dublin.

When finished, the interchange will have seven bridges and more than 100,000 square feet of wall
on 100 acres. Nearly 150,000 vehicles pass between I-270 and Rt. 33 at the interchange each
day.

Dublin officials have said they expected to treat the rebuild as a piece of public art. Months
of public input showed that the nature themes were the most popular, Ott said. “The feeling was
that the Scioto River was here long before any of these manmade structures. Having those scenes on
the walls will really create a sense of place.”

Construction of the interchange could begin as soon as late 2014. When it is finished, two loop
ramps that now force traffic to weave in and out will be gone. ODOT, the Mid-Ohio Regional Planning
Commission and Dublin are paying for the work.
